Why not to use the best of OE BMW CCV and just implement what was suggested by our GURU CNN long time ago

If the Intake Manifold sits above the Valve Cover, then the design is simple.

Reuse OE CCV + implement CNN suggestion to have Manifold above the Valve Cover by another connector from Valve Cover to Manifold

You will have the best of both , - no oil coming into CCV due to U-turn and right vacuum pressure designed by BMW !

I would first try this SIMPLE solution before anything else !!

You could accomplish what you are proposing by simply adding a Check-Valve at the hose from the Valve Cover, to the CCV.
